Chapter 1: the ghost town
The episode will start with Lee and Kenny leaving the Motel, looking for medicines and items in town. When Kenny breaks the ladder, you'll need to reach the nearby jeep and use the winch twice to solve this simple puzzle. Hold on to Kenny's hand to finish the operation.
KEY CHOICE: once you go up with Kenny you will see in the distance a woman attacked by zombies. You can't save her, but you'll have to decide whether to kill her and alleviate her suffering (preventing her from turning into a zombie) or to leave her alive instead, so that she distracts the walking dead as you enter the pharmacy. If you don't kill the woman, the zombies will be slow in coming and you will have more time to collect items inside.
Once inside, collect all the medicines you find, then take cover behind the counter as the zombies enter, and get through the Quick Time Event to escape, using the refrigerator to lock the door. Now complete a second QTE to get rid of the zombie pilot and exit the pharmacy.
Back at the motel, talk to Lilly, who will argue with Kenny as usual. Then go outside to talk to the latter, Carley and Katjaa and finally return to Lilly who will ask you to investigate the other members of the group. Whether or not you agree to help the woman, you will still have to investigate: take the broken flashlight from her, then go out and decide whether to get help from Duck or not. Then talk to Carley, deciding whether to reveal your past to the group or not. However, you can decide in between, telling your story only to certain members and not to others.
Walk around the courtyard asking questions of Clementine, Katjaa, Kenny and Ben (the latter may or may not tell the truth about you), then continue to the end of the Motel to find the remains of the broken torch glass given to you by Lilly on the ground. Follow the glass shards and examine the X on the wall, then go back to Clementine to ask if she drew it in chalk, and talk to Duck to examine the secret passage. Decide whether to give the child a high five or not (his estimate for you will increase if you do), then examine the chalk writing next to the litter, also passing outside to look at everything from the street. Open the small grate and examine the interior, then go inside to go to Lilly to report your findings. At this point the bandits will attack the Motel and Lilly will ask you to create a diversion while the group organizes the defense: ask them why they behave this way and if it is possible to reach a peaceful agreement, then when the shooting starts help to eliminate the enemies with your rifle. Then help Carley to eliminate the zombies that will attack after the bandits, to allow the group to leave the Motel.
Chapter 2: fight on the street
When the group starts arguing, drop Lilly or try to calm her down; do the same with Ben, then deciding whether to be on Lilly's or Carley's side.
KEY CHOICE: after the facts shown, decide whether to leave Lilly on the street or take her with you anyway. Then go back into Kenny's RV where you will talk to him and his wife Katjaa. Also talk to Clementine about what happened. Get over Lee's nightmare to get to where the road is blocked by the train.
Chapter 3: the train
Talk to the group, then examine the train with Ben. Collect the map from the (apparently uninhabited) shelter, then get the water bottle for Katjaa. Then examine the locomotive and the dead driver, then Ben will activate the emergency brake. Talk to Kenny, then examine the control console and the notebook nearby, which will shortly reveal the controls to start the engine. Go back outside, give Katjaa water, ask Clementine for her coloring pencils and go back to Kenny's camper to pick up the pencil (near the driver's seat). Now go back to the locomotive and scribble the previously examined block with a pencil to bring up the ignition sequence. Examine the compartments outside the locomotive, collect the items inside (there is a wrench), then apply the newly discovered sequence on the center panel and on the panel inside the locomotive. Exit again and open the left compartment: start the engines by moving the switch “9” to the left and then to the right. Return to the pair of cars and use the wrench, then return to the wagon and talk to the stranger. Then talk to the group of survivors and Kenny and Katjaa to get everyone on board. Go to the locomotive and use the throttle lever to start the train.
Chapter 4: the train stops
Talk to Chuck, then Katjaa, to pick up the cloth drape from the ground and use it on Duck's face. Katjaa will ask you to stop the train: do it by showing Kenny the bloody cloth.
KEY CHOICE: to stop the train you will have to order Kenny to stop, or make him think with good manners. Also, a second key choice will follow the previous one: talk to Kenny and Katjaa to decide who will be responsible for killing the child, who is about to turn into a zombie. If you choose to pull the trigger, Kenny will remember.
Chapter 5: the plan
Talk to Clem, Chuck, Kenny and ben. Then go to Chuck's wagon and get the whiskey and scissors (from his bag). Go back to Clementine, teach her to shoot and cut her hair explaining that it is to protect her from zombies. Talk to Kenny, then go outside and give Chuck a sip of the previously collected bottle, then go back inside to Kenny and offer him a sip too. Collect the map from the basket and go to Clementine.
When the train stops, go up the ladder and talk to Christa and Omid, then examine the surroundings, collect the objects present and return below. Then go with Clementine to the station: examine the surroundings and, letting the child enter through the window, wait for the door to open and enter. Examine the interior and use the same tactic for the next door, helping Clem slip between the wooden beams. Fight the two zombies with the wrench, then talk to Clementine and get the keys. Unlock the door and aim the gun through the net to kill the zombies. Talk to Christa now, collect the blowtorch and talk to Clementine again.
Now go up on the bridge and use the blowtorch to clear the passage to the train, eventually having Omid help you, who will hold you while you lean out. When the train starts moving, kick the blowtorch to ignite the fuel truck and prevent the zombie horde from reaching you as you jump onto the moving train. Choose whether to push Christa or Omid first. Watch the final cutscene to complete the episode.
